T0 aZZ whom, t may con/cern.-

Beit known that I, AUGUSTIN ELLIS, a citizen of the United States,residing at Bedford, in the county of Lawrence and State of Indiana,have invented certain new and useful Improvements in Cultivators, ofwhich the following is a speciiication.

The principal object of my said invention is to produce a cultivator inwhich the plows are adjustable toward and from each other, and in whichthe plow-beams are Inaintained in parallel relation at wh ateverdistance apart they may be placed. This object is accomplished bysuspending the hangers upon the axle (or a transverse rod connectedthereto or to the frame-work) in such a manner that they may be readilyshifted from one position to another thereon, and combining therewithjointed levers which extend back and unite with standards extending upfrom the rear end of the plow-beams, and which also continue on to formthe handles.

The invention further consists in certain details of construction andarrangements of parts, as will hereinafter be more particularlydescribed and claimed.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figurel is a perspective view of a cultivator embodying Iny said invention,the pole being broken away and the wheels shown in dotted lines; Fig. 2,a top or plan view of the same; Fig. 3, an enlarged plan of the jointedportion of one of the levers which operate the hangers and adjustingparts, on an enlarged scale; Fig. 4, a central sectional view thereof onthe dotted line 4 4 5 and Fig. 5, a transverse sectional view on thedotted line 5 5, and showing especially the particular method which Iprefer to employ in mounting the hangers upon the axle or shaft.

In said drawings, the portion marked A represents the axle or shaft ofthe cultivator, which is shown as of the variety known as an archedaxle; B, the pole thereto; C, the hangers D, the plow -beams, and E thejointed levers by which the hangers and plow-beams are shifted from sideto side in adj listing the plows toward and from each other.

The axle A is not. dissimilar to other arched axles, and needs nospecial description. Upon its ends are the usual wheels A, and runningfrom points near said wheels to the pole B, or a cross-bar B thereon,are brace-rods Z9', by which the rigidity of the structure ismaintained. It is united centrally to said pole by a cap or clip d. Fromalongside said cap or clip to the ends, or the points where it turns,are portions adapted to receive the hangers O, and upon which saidhangers will freely slide or move.

The pole B is in itself an ordinary pole. It is secured to the axle A,as has just been described. Upon its rear end,which projects to the rearside of the axle, is a cross-bar B2, which is extended or is providedwith wings b2, upon the ends of which the hinged lever is pivoted.

The hangers O are preferably mounted on the horizontal portions of theaxle A, although they may be mounted upon separate shafts or a cross-rodsecured to any portion of the frame-work, if desired. To their lowerends are connected the forward ends of the plowbeams, as is common. Theupper ends of these hangers are preferably bifurcated, and pass astridethe axle (or the rod or shaft) upon which they are mounted, and haverollers c placed thereon above and below said axle or shaft, as shownmost plainly in Figs. 4 and 5. The faces of these rollers are concave,so as to fit upon the sides of the shaft and properly engage therewith,and also to permit the slight rotation of said shaft in relation to thehangers, which is desirable. This enables the hangers to be moved to anydesired position with but slight effort on the part of the operator.

The plow-beams D are secured to the lower ends of the hangers C in anordinary manner, and to said plow-beams are secured draftrods CZ, whichextend forward and are attached to singletrees, which are preferablysuspended from the cross-bar B as shown. To the rear end of saidplow-beams, or to wings CZ thereon, are secured the shovels or plows D',and extending upwardly from near the points where said shovels or plowsare attached are arms D2, the upper ends of which pass through slots inthe handle portions of the hinged 1evers E, and upon the extreme upperends of ICO these arms are nuts or caps cl2, by which they are held inplace.

The jointed levers are in two parts, which are respectively pivoted tothe wings of crossbar B2 by pivots e e2. One of these parts has a slotin the end which is next the other part, and said other part has a pine, which engages in said slot. Those parts which eX- tend forward overthe axle engage with upward projections c2 on the hangers C, and theother parts extend back and develop into the handles of the cultivators.The handle portions are preferably hinged at e3, as shown,to permit ofthe freer movement of the machine.

As is well known, it is frequently desired to vary the distance betweenthe plows of a cultivator in operation to accommodate it to rows ofvarious widths or plants of various sizes. It is desirable that in theadjustment of the machine the plow-beams should be maintained inparallel (or substantially parallel) relation, in order that the draftmay be substantially directly forward from the plows. By the use of myinvention the adjustment is effected by simply moving the handles toward or from each other, which, by means of the engagement of thejointed leversE at the forward ends with the upward projection c2 on thehangers and at the rear ends with the upper ends of the arms D2, causeboth ends of the plow-beams to be moved simultaneously and substantiallyto the same extent, thus maintaining the parallel relation, as abovestated.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. The combination, in a cultivator, of the plow-beams, hangers andarmsfor said plowbeams, and jointed levers connected thereto at thefront and rear, whereby by moving said levers both ends of saidplow-beams are moved simultaneously, substantially as set forth.

2. The combination, in a cultivator, of the plow-beams, arms extendingupwardly from said plow-beams, hangers whereby said plowbeams areconnected to the axle or shaft, and jointed levers pivoted to theframe-work and connected at the forward and rear ends, re

spectiVely, with said hangers and said upwardlyprojecting arms,substantially as described, and for the purposeas specified.

3. The combination, in a cultivator, of the hanger C, suspended to theaxle or a shaft, a plow-beam D, connected to said hanger and having anupwardly-projecting arm at its other' end, and a jointed lever E,pivoted to the frame-work and att-ached to said hanger and saidupwardly-projecting arm,said lever being formed in two parts, whichengage with each other by means of a projection and a slot,substantially as and for the purpose set forth.

In witness whereof I have hereunto set my hand and seal, atCrawfordsville, Indiana, this 31st day of May, A. D. 1889. I

AUGUSTIN ELLIS. [1.. s]
